start-transcript导致脚本在后台作业中失败

Question

我使用start-job创建一个powershell脚本作为后台作业,然后使用start-transcript记录它的输出.以下是两者的代码:

一个

start-job  -filepath ./b.ps1 -ArgumentList 'test.txt'
wait-job *

b

param([parameter(Mandatory = $true)][string]$logfile)
Set-PSDebug -Strict
$ErrorActionPreference = 'Stop'
start-transcript $logfile

输出./a.ps1

Id              Name            State      HasMoreData     Location             Command                  
--              ----            -----      -----------     --------             -------                  
1               Job1            Running    True            localhost            param...                 
1               Job1            Failed     False           localhost            param...                 
2               Job2            Failed     False           localhost            param...   

输出./b.ps1 -log c:\ test.txt

Transcript started, output file is test.txt
Transcript stopped, output file is C:\test.txt

我还通过设置"echo here"行来做一些测试,以确认是播放的行.

显然,后台作业不支持Start-Transcript.如果您执行Receive-Job查看脚本输出,您可能会看到如下错误:

This host does not support transcription.
    + CategoryInfo          : NotImplemented: (:) [Start-Transcript], PSNotSupportedException
    + FullyQualifiedErrorId : NotSupported,Microsoft.PowerShell.Commands.StartTranscriptCommand

在PowerShell 2.0中我推荐你切换Set-PSDebug -strict到Set-StrictMode -Version 2.0- 它会捕获更多潜在的错误.
